Problems solved by technology

The purpose of removing vanadium is not only for decolorization, but more importantly because It contains oxygen atoms, so the main purpose of removing vanadium is to remove oxygen. At present, chemical methods are used to remove vanadium in industrial production. There are four methods: copper wire, aluminum powder, hydrogen sulfide and organic matter. At present, most of them use two-step methods, namely The vanadium removal process is completed in two steps: the preparation of titanium trichloride slurry and the removal of vanadium in the slurry. This method has a complicated process, a large amount of aluminum powder consumption and a large amount of vanadium removal residue, and there are unsafe factors in the reaction process.

Embodiment Construction

[0014] The method for refining titanium tetrachloride by removing vanadium from aluminum powder of the present invention comprises the following steps:

[0015] ① The crude titanium tetrachloride test solution removes high-boiling impurities, and the generated impurities flow into the residue liquid container;

[0016] ② The crude titanium tetrachloride test solution removes low-boiling impurities, and the resulting distillate is further processed;

[0017] ③ Add aluminum powder and clear liquid to the crude titanium tetrachloride test liquid, remove vanadium and aluminum to obtain refined titanium tetrachloride, and the residue liquid enters the residue liquid container;

[0018] ④The residue liquid is settled to obtain a clear liquid and an underflow, the clear liquid is used for vanadium and aluminum removal, and the underflow can be further purified;

[0019] The method for removing vanadium and refining titanium tetrachloride from aluminum powder of the present invention...

Abstract

The invention relates to the field of chemical engineering, and particularly relates to a method for refining titanium tetrachloride by removing vanadium through aluminum powder. The method comprises the following steps: removing high-boiling-point impurities from a crude titanium tetrachloride test solution, removing low-boiling-point impurities from the crude titanium tetrachloride test solution, adding aluminum powder and a clear solution into the crude titanium tetrachloride test solution, removing vanadium and aluminum to obtain refined titanium tetrachloride, and settling the residual solution to obtain the clear solution and underflow, wherein the clear solution can be used for removing vanadium and aluminum, and the underflow can be further purified. The method for refining titanium tetrachloride by removing vanadium through aluminum powder is steady in chemical reaction process, high in safety and simplified in procedures, and the amount of the aluminum powder and the amount of vanadium removal residuals can be greatly decreased.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for refining titanium tetrachloride by removing vanadium from aluminum powder. technical background [0002] thick The vanadium impurities in the form exists so that It is yellow. The purpose of removing vanadium is not only for decolorization, but more importantly because It contains oxygen atoms, so the main purpose of removing vanadium is to remove oxygen. At present, chemical methods are used to remove vanadium in industrial production. There are four methods: copper wire, aluminum powder, hydrogen sulfide and organic matter. At present, most of them use two-step methods, namely The vanadium removal process is completed in two steps of titanium trichloride slurry preparation and slurry vanadium removal. This method has complex process flow, large consumption of aluminum powder and large amount of vanadium removal residue, and there are unsafe factors in t...
